Step Task Expected Results
1
AQUISITION:
• 3D STATIC
3D Volume Mode - Static volume acquisition (also in combination with PD, HD-Flow or CFM)
• 4D REAL TIME
Real Time 4D - continuous volume acquisition and parallel calculation of 3D rendered images
• VCI A-PLANE
Volume Contrast Imaging - improves the contrast resolution and the signal / noise ratio and
therefore facilitates finding of diffuse lesions in organs
• VCI C-PLANE
Volume Contrast Imaging (coronal plane) - improves the contrast resolution and the signal /
noise ratio and therefore facilitates finding of diffuse lesions in organs
• DIAGNOSTIC
The fetal heart or an artery can be visualized in 4D (also in combination with PD, HD-Flow or
CFM)
• 4D BIOPSY
Real Time 4D Biopsy - continuous volume acquisition + parallel calculation of 3D rendered
images
2
VISUALIZATION:
• VOCAL
The basic idea behind VOCAL II is the combination of 3D ultrasound tissue (presented as
voxels) and the geometric information of surfaces in a 3D dataset. After definition of contour in
3D space a wide range of functionality is given.
• NICHE
Parts of the orthogonal sections A, B and C are compiled to a 3D-section aspect. The name
“Niche” has been chosen because the aspect shows a quasi spatial cut into the reference
image.
• RENDER
After the 3D acquisition the system switches automatically to the read menu. The selected
format will be present on the monitor (e.g., 3D ROI Mode: sectional planes A, B, C + rendered
3D image).
• SECTIONAL PL.
After the 3D Sectional Planes acquisition the system switches automatically to the read menu.
The selected format will be present on the monitor (e.g., A,B,C - Sectional Plane mode).
3
- Quarter size display of Sectional Planes without 3D image or
- Quarter size display of Sectional Planes + rendered 3D image
(Note:
The display depends on selected Acquisition- and Visualization Mode!)
4
Dual size display of Sectional Planes + rendered 3D image.
(Note:
The display depends on selected Acquisition- and Visualization Mode!
This format is not possible for Static 3D Acquisition)
5
- Full size display of a the reference image or
- Full size display of the rendered 3D image.
(Note:
The display depends on selected Acquisition- and Visualization Mode!)
6
Volume Box Position
and Volume Box Size
Adjust the Volume Box (ROI) Position resp. Size with the TRACKBALL in the 2D Single image.
The upper trackball key
to change the Trackball function from Box Position to Box Size.
7
QUALITY Changes the line density against the acquisition speed (low, mid1, mid2, high1, high2).
8
VOL. ANGLE To select the Volume Sweep Angle.
9
Start Acquisition Press the FREEZE
key resp. the right trackball key to start the Volume acquisition.
